Superb article on Space

article from New Scientist about the world being a hologram

According to Craig Hogan, a physicist at the Fermilab particle physics lab in Batavia, Illinois, GEO600 has stumbled upon the fundamental limit of space-time - the point where space-time stops behaving like the smooth continuum Einstein described and instead dissolves into "grains", just as a newspaper photograph dissolves into dots as you zoom in. (..) If this doesn't blow your socks off, then Hogan, who has just been appointed director of Fermilab's Center for Particle Astrophysics, has an even bigger shock in store: "If the GEO600 result is what I suspect it is, then we are all living in a giant cosmic hologram."

A noise floor found in very small measurements means that our entire universe could be holographic. If true, this could have wide-ranging applications in space exploration, physics, computer science, philosophy, and other fields.

"The idea that we live in a hologram probably sounds absurd, but it is a natural extension of our best understanding of black holes, and something with a pretty firm theoretical footing. It has also been surprisingly helpful for physicists wrestling with theories of how the universe works at its most fundamental level."

Feeling small

Ok. Now I feel small. Start at the top of the image and work your way down. http://is.gd/sgZ4 [from http://twitter.com/teachernz/statuses/1516861582]

A great article. Every thing is perception. i beleive in it

Review of Biocentrism in the Discover magazine

The farther we peer into space, the more we realize that the nature of the universe cannot be understood fully by inspecting spiral galaxies or watching distant supernovas. It lies deeper. It involves our very selves.

Few topics interest me more than space. Though I'll admit that I don't know nearly as much as I would like, it has always been my goal to learn about the universe. I bet I'm not alone. That's why I'm sharing this list of 18 space sites. They all offer something neat. And they're all informative.

Watch an incredible travel to the end of the universe and back. http://bit.ly/5lNzl1

Amazing flash animation where you choose the scale with a slider and it zooms from quantum foam to the entire universe. Spectacular. [via Math Hombre blog]

Zoom from the edge of the universe to the quantum foam of spacetime and learn the scale of things along the way!

A cool look at why we view the world we do and why certain actions can't be reversed.

Our universe may have started not with a big bang but with a big bounce—an implosion that triggered an explosion, all driven by exotic quantum-gravitational effects

LQC is in fact the first tangible application of another theory called loop quantum gravity, which cunningly combines Einstein's theory of gravity with quantum mechanics. Theories like this work out what happens when microscopic volumes experience an extreme gravitational force, as happened near the big bang, for example. Ashtekar rewrote the equations of general relativity in a quantum-mechanical framework. ABHAY ASHTEKAR saw the universe bounce back while watching a simulation of the universe rewind towards the big bang. Mostly the universe behaved as expected, becoming smaller and denser as the galaxies converged. But then, instead of reaching the big bang "singularity", the universe bounced and started expanding again. The theory that the recycled universe was based on, called loop quantum cosmology (LQC), had managed to illuminate the very birth of the universe - something even Einstein's general theory of relativity fails to do.

"Ashtekar later used this framework to show that the fabric of space-time is woven from loops of gravitational field lines."

Did our cosmos exist before the big bang

Loop Quantum Cosmology posits a different beginning to the universe.

At no point was matter spewing forth from anything. Space and time itself was being created first. Ordinary matter (atoms, molecules etc) was created out of tiny imbalances of energy left over from the inflationary period.

The Big Bang was not an explosion of matter into space, rather it was an explosion of space ITSELF, and since space and time are interconnected, we really have to say it was an explosion of space AND time, or space-time.
